IPCC DDC AR5 ETH Zurich/IPCC AR5 WGI esm experiments


Knutti, Reto

"esmX" are an experiment family of the CMIP5 - Coupled Model Intercomparison Project Phase 5 ( https://pcmdi.llnl.gov/mips/cmip5 ) including esmHistorical, esmrcp85, esmFdbk1, esmFixClim1 and esmFixClim2. CMIP5 is meant to provide a framework for coordinated climate change experiments for the next five years and thus includes simulations for assessment in the IPCC AR5. This subset of the CMIP5 esm data were collected by ETH Zurich until 15th March 2013 in support of IPCC AR5 Working Group 1 ( http://wiki.c2sm.ethz.ch/COSMO/CMIP5 ). These data are part of the IPCC-DDC AR5.

esmX: Variation of CMIP5 experiment with alternate forcing (emissions-forced historical and rcp85) or alternate feedback (CO2 increase feedback on radiation code for esmFdbk1, esmFixClim1/2).
